CHARLES H. BULSON, OF NAPA, CALIFORNIA.

DRAINER FOR WOUNDS.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed. November 14, Seria1No. 731,349.

To all whom it may concern Be it known that I, CHARLES H. BULSON, a citizen of the United States, residing at Napa, in the county of Napa and State of California, have invented certain new and useful Improvements in Drainers for Wounds, of which the following is a specification.

This invention relates to devices for draining or cleaning wounds or sores.

The object of the invention is to provide a simple, cheap and improved device of the character indicated.

The invent-ion consists in the construction hereinafter described and particularly pointed out in the claims.

In the accompanying drawing which illustrates the invention and forms part of the specification:-Figure 1 is a perspective view of the device; Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sect-ion of a modification.

The device as a whole comprises a holder and an absorbent strip of gauze, cloth, porous paper, or the like, carried therein and of suitable form, size and material for being inserted in a wound or sore to drain the cavity. Said strip may or may not be medicated, as well as being absorbent. In its preferred form the holder comprises a plurality of wires or metal strips (1), of silver, nickel, or other suitable metal, bent to U- shape, the difierent bent wires standing in longitudinal planes at right angles to each other, and connected where they cross at the bottom, as at (2), by solder or otherwise. A little above the bottom, say half inch, is secured a cross wire extending substantially diametrically of the holder, being secured at opposite points to one of the wires or metal strips. Numeral 4: denotes a band or disk of metal, rubber, or any suitable material, to which the terminals of said U-wires or strips are suitably secured, for example, by soldering as at 60, cementing or binding.

Adhesive strips 17 passing through the slots 6, 7, may secure the device in place.

The absorbent strip 8 passing down to and under the cross wire 3 (or 30) can be readily slipped along to bring a dry or clean part of the strip to the bottom of the holder, or for complete removal. During the latter operation, by securing a fresh strip to the one being removed, such fresh strip may be substituted for the soiled one. The soiled portion of the used strip will be directly behind one of the side wires of the holder and thus kept from contact with the side of the wound or with the hand of a user. The entering part of the strip will also be kept from the side of the wound and from the users hand. By locating the cross wire (3) as described, a space of suitable capacity is left below the absorbent strip in which blood, pus, or the like, gathers and from which it is taken by the strip.

In Fig. 3 the cross bar 30 for the absorbent strip to pass under is mounted in a glass or other suitable tube. Said tube is also provided with slots 62 at the top for securing tapes.

The device will be made in difierent sizes according to the use for which it is intended, say from two to six inches in length. The cross bar (3), located above the bottom of the holder, is applicable and useful with other forms of holder than the particular wire or glass holders described, and is within my invention. It is preferred to have the side portions of the frame wires parallel, but a small departure therefrom will not avoid the invention.

Having described the invention, what I claim and desire to secure by Letters Patent of the United States, is

1. A drainage device comprising a holder having an interior cross piece near the bottom, and having a top inlet and outlet for an absorbent strip, and such strip entering the holder, passing under the cross wire, and out at the top of the holder, the cross piece being adapted to permit easy sliding of the strip when an end thereof is pulled.

2. A drainage device comprising an open wire frame made of a plurality of U-shape wires secured together, and in planes at an angle to each other, a cross piece a little above the bottom forming a guide under which an absorbent strip may be passed, as set forth. 7

3. A drainage device comprising a frame made of a plurality of U-shape wires secured together, and in planes at an angle to each other, a cross piece a little above the bottom forming a guide, and an absorbent strip passing under said cross piece.
